Took my truck to ford last week for some warranty work. I thought my oil cooler was for sure shot, as i have seen deltas as high as 30 degrees. i figured egr was shot because of puking coolant, and probably headgaskets because of overheating. Just got a call from service dept. telling me I need 2 new batteries (they were fine when i dropped the truck off), but that's unrelated. While on the phone i asked for an update on my truck since i hadn't heard from them at all. I was told they replaced head gaskets, but everything else is fine, oil cooler and egr etc., only other thing is they are gonna flush the cooling system. Now i am far from being a mechanic, but from research i've done on the org i was thinking the oil cooler was the culprit of the high deltas, and that was the start of the chain reaction that leads to the headgaskets? And the headgaskets are the cause of the overheating? Am i getting screwed or do i just not know what i'm talking about?

If your deltas were over 15* apart then your oil cooler IS clogged and NEEDS to be replaced!!!

Also, the reason you blew the gaskets is the oil cooler stopped coolant flow to the EGR cooler and the Egr cooler flash boiled and ruptured and sent coolant into you cylinders causing the heads to rise...

thanks for the replies guys. how do i get them to fix it right when they say there is nothing wrong? i have i never dealt with warranty stuff before and they fought with me for a couple of weeks before they would even honor the warranty. i am ready to have my truck back, but i want it to be fixed to right

Despite my best arguments, the dealer wouldn't replace my oil cooler. I finally got them to agree to install a "black box recorder" on the truck and I would push the button when it was having the issue (in my case, that was a strong coolant odor through the AC vents while towing, which was an indicator in the three prior EGR cooler failures that they were blown.) They FINALLY got enough information to allow them to replace the oil cooler and EGR cooler under warranty.

See if they can get one of those recorders that plugs into your OBD-II port.

i have never heard of that but i like the idea (if it will prove to them that somethings wrong), i will see if i can get them to put one in for me, thanks for the advice.

I know this sounds crazy(sarcasim intended) but what about a test drive...
I think that would answer their questions about the oil cooler. If they would just go test drive the freikin truck they would find the spread...

The work that goes on in these dealers is VERY frusterating!! They couldnt care less about actually fixing the truck. Especially after a major job like head gaskets there should be an extensive test drive after the repair to make sure all is well.

It's like they don't think a step in advance AT ALL!!! If they put it all together and realize that the oil cooler is bad, they have to tear back into it ALL OVER AGAIN... While they could have just changed a $250 part while they were in there already
